AUTOMATIC SASH-HOLDER.

Specification of Letters Patent.

Patented Feb. 6, 1917..

Application filed March 14, 1916. Serial No. 84,224.

To all whom it may concern:

Be it known that I, NORMAN H. SMITH, a citizen of the United States, residing at Babylon, in the county of Sulfolk, State of New York, have invented certain new and useful Improvements in Automatic Sash- Holders; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to sash holders, having particular reference to improved means for supporting a window sash at any particular point in the extent of its sliding movement. 1

The primary object of the invention is to provide means applicable to the usual well known slidable sash, for holding the sash securely against the sash confining bead to prevent rattling of the sash within the frame, and to prevent air gaining access to the interior of the building through the usual crevices at the juncture of the sash with the frame.

A further object of the invention is to provide means for accomplishing the above mentioned ends which is of simple and inexpensive construction, which may be easily and quickly applied to the ordinary slidable sash without the use of special skill or tools, which when applied ,will be invisible, and which is so arranged as to preclude the possibility of the device becoming broken or out of order and which will prove thoroughly practical and eflicient for the purposes for which it is designed.

With these objects in view, together with others which will appear as the description proceeds, the invention resides in the novel combination and arrangement of parts, all as will be described more fully hereinafter, illustrated in the drawings and particularly pointed out in the claim.

The invention will be best understood by reference to the accompanying drawings, wherein:

Figure 1, is a vertical sectional view taken through a portion of the stile of a conventional form of window sash and illustrating the application of a device embodying my invention, Fig. 2, is a sectional view taken substantially on line 2-2 of Fig. 1, and Figs. 3 and 4 are perspective views ofthe parts of the device removed from the sash.

Referring now more particularly to the drawings, 5 indicates a stile of a window sash, the same being mounted for vertical sliding movement between the parting strip 6 and inside bead 7 of the frame as shown. The outer surface of the stile 5, or that side of the stile lying adjacent the parting strip 6, is cut away to form a pocket for the reception of a plate forming a shell 8. This shell may be formed of thin narrow metal, being straight for the greater portion of its extent,'and being bent at its ends outwardly and inwardly as shown to provide an inturned flange 9, forming with the adjacent portion of the metallic plate a housing 10. The opposite vertical stiles of the sash are equipped with the shells as above described, the said shells extending longitudinally of each of the stiles. The inturned flanges 9 at each end of the shells lie flush with the .outer surface of the stile, and retaining screws 11 are driven through said flanges, through the housing portion, and through the next adjacent thickness of the shell plate to engage within the wood of the stile to retain the shell in position.

A strip 12, preferably of spring steel, has its ends confined within the housings 10 at each end of the shell, the said spring strip being bowed normally outwardly to engage with the adjacent surface of the parting strip 6. The ends of the spring strip engage with the retaining screws 11 passing through the housings l0, and to efiectuate a proper seating of the strip ends, the latter may be bifurcated as at 13 to engage around the said retaining elements. The strips 12 are preferably of a width equal to that of the plate 8 constituting the shell, and it is obvious that engagement of the bowed portion of the strip 12 with the adjacent parting strip will cause the window sash to be firmly seated at its inner edges with the inner bead 7 of the frame. A coil spring 14 may be arranged within the shell, preferably midway the ends thereof, to exert outward pressure upon the spring strip 12, the said spring being secured to the said strip by means of a retaining'screw 15, and being seated at its opposite end against the inner face of the shell 8. The screw 15 may be countersunk in the said strip to prevent scarring or wearing away of the partingstrip 6.

It is obvious from this description that a device so constructed will act as an etlicient anti-rattling device, andby yieldably holding the shell against the beading the entrance of air to the building through the window joint will be precluded. It will bers 11 assists in retaining the latter against becoming detached from the shell.

While I have herein shown and described a particular or preferred embodiment of the invention, I wish it to be understood that I need not necessarily confine myself to all the precise details of construction herein set forth by way of illustration, as modification and variation may be made without departing from the spirit of the invention or exceeding the scope of the claim.

I claim:

A sash holder, comprising in combination, a continuous. metallic strip shaped to provide an elongated bottom plate, vertical ends at each end of said bottom plate, and inwardly faced recesses formed on the free extremities of said ends, an outwardly bowed spring strip having its ends inserted in said recesses and bridging said ends and a coil spring interposed between said bottom plate and the bowed portion of said spring strip, the inserted ends of said spring strip being longitudinally notched to surround the fastening screws passed through the walls of said recesses to secure the device to a sash.

In testimony whereof, I affix my signature, in the presence of two witnesses.
